A collection of our favorite quotes from the early rounds of the Sony Open:

• "My advice is you've got to make sure you wear the clothes and not [let] the clothes wear you. It's quite simple in a way. Don't wear something you totally feel uncomfortable with, but take some chances. Play around a bit. I felt very uncomfortable in suits when I was younger, so what I just started doing was wearing suits when I was going to dinner. I used to overdress a little bit so I got used to wearing suits. Now wearing a suit is like wearing a track suit for me. So it's all good."

-- Roger Federer, on his fashion advice for the fellas.

• "I have been on TV so many times that once is OK for me."

-- Maria Sharapova, on whether she was disappointed or surprised that her opening-round prime-time match on Stadium Court wasn't televised.

• "It is a relief for me, because I haven't had a title this year up to Indian Wells. The Indian Wells final was the first final of the year. I haven't played many tournaments; I haven't played many matches. So I knew I'm playing well. I had an incredible end of 2013, so I did have confidence. But I started a little bit doubting myself on the court. I was struggling a little bit with my consistency and the concentration. Throughout the tournament also I had ups and downs, but I managed to win four out of six matches in three sets. Mentally, it's a very encouraging win that gives me confidence and that also is very special in a way. This time of the year I needed it very much, and hopefully I can carry that into this week."

-- Novak Djokovic, on the importance of winning the BNP Paribas Open.

• "To tell you the truth, I totally forgot. [The ATP's Greg] Sharko came up to me in the locker room. Today was just like another match and an opportunity to go out there and play well. Yeah, obviously afterward, a great milestone. Not many people get to achieve that. Not many people get the opportunity to get close that, so it means I have been around for an awfully long time, as well. I'm getting old."

-- Lleyton Hewitt, 33, after beating Robin Haase in the first round for his 600th career victory.

• "If I go down, it's never easy. At least my opponent knows they have to go to the end of the earth to take me out no matter what the circumstances. I do try to compete. Even if it's not your best day, I just try to walk off the court knowing I gave 100,000 percent."

-- Venus Williams, on her reputation as a competitor.

• "Just a really disappointing night. Just got my butt kicked, and that's about it really."

-- Sloane Stephens, after her 6-0, 6-1 loss to Caroline Wozniacki.

• Sloane Stephens was heavily criticized by Mary Carillo and Rennae Stubbs during the Tennis Channel broadcast of her loss to Wozniacki:

Q. There were some harsh words on Tennis Channel saying they were not sure if you were trying to act cool or if you didn't care tonight during the match. What would you say in response to that?

Stephens: No comment.

• "Obviously, I wasn't at my best. I had 40‑ something errors. It's not the way to play professional tennis. Maybe amateur."

-- An unhappy Serena Williams, after struggling through a 6-4, 4-6, 6-4 win over Caroline Garcia.

• "It was my third time already, so maybe she was a little bit smaller than the previous one [smiling]. But, no, I just try to forget it's Serena Williams, to forget that she won how many Grand Slams, and just be me and just play."

-- Caroline Garcia, on not being intimidated by the prospect of playing Serena.

• "I feel I do have easier power. It's actually a big switch, bigger than people think it is, because it's a much bigger head frame, it's a wider beam, and I really enjoy this new racket. I think it's definitely also part of the reason that I am playing so well right now."

-- Roger Federer, on the changes to his new racket. He also said he's still tinkering with it and hopes to finalize something within the next month.

• "I think he's going to be out in his car in the parking and lot and not even watching the match."

-- Madison Keys, when asked whom her agent, Max Eisenbud, would be rooting for in her third-round match against Li Na, another Eisenbud client.

• "I feel most important is the work ethic and making sure that the kids you are training with understand that it's not just the coach's job to motivate them or that if you win a junior tournament you're actually great. You're far away from it. You have to keep working hard. ... [Y]ou can't have the parents and the coaches make you feel good all the time. You have to make sacrifices. I left home at 14 years old, stopped school at 16 and went on tour. I had a hard time understanding what hard work was, but eventually I figured it out, thankfully, early enough. If the kids don't understand and don't want to put in the hard work -- I'm not talking about just hanging around the courts and playing for four hours a day; it's about working well and quality -- they will never get anywhere. It's just very simple."

-- Roger Federer, when asked about youth tennis and how the U.S. men can re-establish their dominance.

• Maria Sharapova was shown a video of fans who were asked whether they thought she was pretty or tough. It led to an awkward moment on the court but a pretty good one off the court:

Q: Would you rather be considered pretty or tough?

Sharapova: I'd rather be considered pretty tough.

• "Partially realizing there is another tournament next week -- you can go and you can work on stuff and you can get better. But then it's also just looking back three years ago and remembering these devastating losses and realizing, I'm here right now. You know, the world didn't end. I didn't have to quit tennis. Life continues."

-- Madison Keys on learning to control her negative emotions after tough losses. "I'm growing," she says.

• "Everyone was talking to me about this, not my match, how I play. Just, Murray say you will be No. 1. And I was like 150 in the world, so it was not easy when you're like 17 years old and you are nowhere and someone will say you will be No. 1. [But] I'm happy he says this, because it's always good comments from someone like Andy."

-- Caroline Garcia, on Andy Murray's claims three years ago that she would be a future No. 1. Garcia, 20, is ranked 74th.

• Li Na apparently has some fancy nail paint this week that matches her new Nike kit. Which led to this exchange:

Q: Have you ever talked to Serena about nails? She's like a certified professional nail person.

Li: I think the professional for the tour is [Agnieszka] Radwanska. I think she do pretty. Really. She do herself.

• "Only my wife knows. If I knew, I wouldn't tell you."-- Roger Federer, when asked if he knew wife Mirka's due date.
